Server with too many port 80 connections

[SalvadorS]

Hello,

We have a server with plesk with a lot of http connection to port 80 (load of the server goes up to 500 in minutes)

I try to search one of the IPs to see to what domain goes the connections but I can´t find anything:

grep 103.23.108.224 /var/www/vhosts/*/logs/access_log

And no results

Also check logs under /var/logs/apache2 and nothing...

Can anybody help me to find where these connections are hitting?

If I can find a log I can confiig fail2ban for example but no logs found...

Any suggestions?

Thanks
